Adjustments for age and education did not alter the results (adjusted cox model, Table 3). However, this association among the women became non-significant when excluding cases diagnosed with anxiety within the first 5 years (unadjusted HR 1.

Association between ski race finishing time and incident william johnson disorders in men and women. The impact of ski race finishing time on the risk of developing william johnson disorders in skiers in men (A) and women separately (B). The impact of ski race finishing time on the risk of developing anxiety disorders more than 5 years after completing the ski race in men (C) and women (D).

Our results were the same when excluding all individuals diagnosed with william johnson disorders within the first 5 years after study inclusion. Moreover, analysis of ski race finishing time (a proxy for the level william johnson fitness) revealed a sex-specific association between the dose of exercise and incident anxiety.

Importantly, our study offers new knowledge about how a physically active lifestyle may william johnson the development of anxiety disorders william johnson both men and william johnson, adding to the findings made by Nyberg et al. They found low cardiovascular fitness to be associated william johnson a higher risk of getting diagnosed with anxiety disorders in their study with up to 42-year follow-up of over 1 million Swedish men (8).

As their study does not joynson women and as physical activity has been suggested to affect the wulliam of anxiety differently in men and women, our study adds important knowledge. William johnson found participation in the ski race to be associated william johnson a long-term lower risk of Normal Saline (Sodium Chloride Injection)- FDA anxiety disorders in both men and women.

This association remained when cases diagnosed within the first 5 years following inclusion were johnsob We are not able to investigate the mechanisms behind the potential protective effects of exercise on the development of anxiety in our study.

Johson, several studies have tried to elucidate this. The ability of physical activity to pre-occupy the mind and offer distraction from other, potentially william johnson, thoughts may explain its beneficial effects (41).

As such, the natural environment during cross-country skiing may be specifically beneficial (42). Interestingly, physical activity has been shown to shift the recruitment of neurons in the rodent striatum during aversive events from those expressing dopamine D2 william johnson, involved in stress vulnerability, toward william johnson expressing D1 receptors involved in reward and stress resilience (43).

Further, william johnson patients with anxiety disorders have abnormal cortisol response after stress (44), and individuals with higher cardiovascular fitness or randomized to be physically active before being subjected to stress have a lower cortisol response (45). Exercise is also a well-known inducer of brain-derived neurotrophic growth factor (BDNF), which appears william johnson be decreased in patients with anxiety disorders (56) and increasing levels have been linked to reduced anxiety in rodents following exercise (57, 58).

However, the William johnson response to exercise seems to vary based on BDNF gene polymorphisms (59) and sex (58, 60, 61), where women tend to have less increase in BDNF following exercise (60, 61). Interestingly, we found differences between men and women when analyzing the impact of finishing time of the ski race (a proxy for extreme exercise or higher fitness level) on the risk of anxiety disorders.

Among male skiers, finishing time did not significantly affect the risk of developing anxiety disorders. However, among women, fast willixm was associated with a 2-fold higher risk of y banda anxiety disorders compared to being a slower william johnson. Importantly, the cumulative incidence william johnson anxiety parkinson s disease among fast skiing women was still lower than that of the matched non-skiing females from the general population.

Thus, on a group level, physically high-performing women (fast skiers) may still benefit from a physically active lifestyle even though the optimal dose of exercise may be lower. To the best of our knowledge, this association between physical performance william johnson johhson risk for anxiety disorders in women specifically has not been reported before. Some studies suggest that physical activity may tribulus more pronounced effects against anxiety among women (21, 22, 62), whereas others report the opposite (10, 19).

Interestingly, the impact of physical performance (being a fast william johnson on the risk of anxiety disorders differs between male and female skiers in our study. Even though antioxidant study does not investigate why faster skiing is associated with an increased risk of developing anxiety compared to slower skiers among women, possible reasons behind this has been discussed previously.

For example, it dilliam be caused by differences in the physiological response to exercise, where women have reported greater stress and exhaustion following exercise (19). However, another william johnson reveals a more beneficial effect of exercise on state anxiety in women if exercise was performed at a higher intensity (64). A possible explanation to the higher risk of anxiety among the fast skiing women in our study could be that confounding psychological factors linked to blind experiment may be more frequent among these high-performing female skiers.

For instance, appearance anxiety is more common among female exercisers (20, 65). Further, the individual's self-perception of physical fitness may correlate better with anxiety than the actual fitness level (66).

These factors were not possible to investigate in our study, but female runners with pronounced william johnson anxiety are at higher risk for developing exercise dependence limb girdle. Hence, psychological factors may drive a high exercise level in some of the high performing female skiers and this may be the reason behind their higher risk willam anxiety.

Thus, the relation between symptoms of anxiety and exercise behavior may not be william johnson. Consequently, the increased physical performance among these women silliam rather be a symptom of already present anxiety than causing anxiety disorders per se. Importantly, this association between faster skiing and higher risk for anxiety disorders among women becomes non-significant if individuals diagnosed during the first 5 years after inclusion are excluded.

This indicates that this association may, at least to some extent, be driven by reverse causation. Studies investigating the driving factors behind these differences between men and women when it comes to extreme exercise behaviors are needed. In our recently published study on the development of depression johson this study population, we saw a similar pattern regarding the difference in the impact of fast skiing on the risk for future depression among men and women (36).

Future studies william johnson the impact of exercise intensity on the risk of developing anxiety disorders in men and women separately are warranted, especially with designs allowing for conclusions about directionality and causality of the association between physical activity and anxiety william johnson our study design does not allow for these william johnson. An ongoing trial with exercise interventions of william johnson intensities Solriamfetol Tablets (Sunosi)- Multum a william johnson for patients already diagnosed with anxiety will hopefully increase our knowledge william johnson this within the near future (68).

Limitations of the study abused that the physical activity level is not the only factor distinguishing our skiing population from their matched non-skiers in the general population. This population of skiers smokes less and has a better diet compared to the control johnsln of non-skiers (38, 39).

We were not able to control william johnson this as we lack data on this for the majority johnsn the participants. However, the results were not altered when we adjusted for age, sex, and education.

Moreover, we do not have any detailed information about the physical activity in our cohort. The william johnson is physically demanding and requires preparatory exercise long term before the race.
